note 67832 added to function.imagecopyresampled

For everybody who needs thumbs that are exactly 100x100 or so. The image is cropped to the right proportions, and scaled - simultaneously. (This code doesn't work if you have the bug described below in your installation.) <? /* resize and crop a gd image object to a given height and width */ function resize_and_crop($image, $width=200, $height=200) { $width_orig = imagesx($image); $height_orig = imagesy($image); // Get crop area and offset $scale_factor = max($width / $width_orig, $height / $height_orig); $width_crop = $width / $scale_factor; $height_crop = $height / $scale_factor; $x_offset = 0.5 * ($width_orig - $width_crop); $y_offset = 0.5 * ($height_orig - $height_crop); // Resample $image_p = imagecreatetruecolor($width, $height); imagecopyresampled( // ==target== ==original== $image_p, $image, 0, 0, $x_offset, $y_offset, $width, $height, $width_crop, $height_crop); return $image_p; } ?> ---- Server IP: 129.16.214.50 Probable Submitter: 81.232.139.126 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/function.imagecopyresampled.php Edit -- http://master.php.net/note/edit/67832 Del: integrated -- http://master.php.net/note/delete/67832/integrated Del: useless -- http://master.php.net/note/delete/67832/useless Del: bad code -- http://master.php.net/note/delete/67832/bad+code Del: spam -- http://master.php.net/note/delete/67832/spam Del: non-english -- http://master.php.net/note/delete/67832/non-english Del: in docs -- http://master.php.net/note/delete/67832/in+docs Del: other reasons-- http://master.php.net/note/delete/67832 Reject -- http://master.php.net/note/reject/67832 Search -- http://master.php.net/manage/user-notes.php
